- Where are we in the Universe?
- Where are we going?- Where did life come from, and are we alone?

Currently Huygens, Mars Express and SMART-1 are en route to moons and planets in our Solar System.

The SOHO, Ulysses and Cluster missions are ESA’s contribution to our understanding of the Sun, which helps to maintain our world’s temperature, but it also produces a magnetic field that shields our world from deadly cosmic rays coming from the far depths of space.

The Hubble Space Telescope, XMM-Newton and Integral are orbiting the Earth but they are looking deep into the violent Universe.
